CAR-COUPLiNG.

SPECIFICATION forming part of Letters Patent No. 305,912, datedSeptember 30, 1884.

Application filed March 10, 1884. (No model) I i To all whom it mayconcern:

Be it known that I, BEVLY A. FISHER, of St. James, in the county ofPhelps and State of Missouri, have invented a new and useful Improvementin Self-Couplers for Railway- Cars, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming a part of this specification, in which similar lettersof reference indicate corresponding parts.

Figurel is a section of a double draw-head with myimprovements attached,and showing the parts uncoupled. Fig. 2 is avertical sectional view ofthe same with the coupling-link in position. Fig. 3 is a modificationshowing a single draw head and coupling pin. Fig. 4 are details, of thecoupling-pins and crank-rod. Y,

My invention relates to that class of selfcouplers in which the cars arespeedily and efi'ectively uncoupled from the side of theplatform withoutplacing ones life in danger by, going in between the cars, and is animprovement on Letters Patent No. 285,247, granted to me September 18,1883, for improvements in car-couplings.

To enable others skilled in the art to make and use my invention, I willproceed to describe the exact manner in whichl have carried it out.

in the said drawings, A represents a double draw-head, which is used incoupling cars of different heights, and provided with the on dinaryopenings, at a, which are separated from each other by a partition, a,as shown in Fig. 1, and B is the coupling-link.

Located in the draw-head,and pivoted in the rear of the center ofgravity, are the couplingpins G D, which are constructedsubstantially-as shown in the drawings-that is to say,'the coupling-pinO, which is pivotally secured to the draw-head at the point 1, isconstructed with the curved hooked end, and at the rear with thedownwardlyprojecting arm 0, which is cut away at a point immediatelybelow the pivot to form a recess, in which fits the upwardly -projectiugarm of the lower coupling-link, and is also provided on its projectingarm with a pin, 0, as will be hereinafter more fully set forth. Thelower coup ling-pin, D, a point, 2,

is pivoted within the drawhead at and is constructed with the upwhichworks the pin 0, formed on 'wardlyprojecting arm (I, which has a portionof its surface cut away in a manner similar to the upper coupling'pin,O. The upwardlyprojecting arm dof coupling-pin D is formed with a curvedslot, cl, in its upper end, in the lower arm 0, as shown in Fig.

D is also formed on the rear of the arm (I with a flat step, e, and inthe rear of the coupling-pins O and D is pivotally secured a tumbler, B,so arranged that its short arm 6 will rest upon the flat step formed onthe coupling-pin D, thereby holding the coupling-link in its properposition end of the projecting 1. The coupling-pin within the draw-head.A chain or cord, f, se-

cured at a point. 3, to the tumbler E, passes through an opening inthebottom of the drawhead, and is carried forward and secured to thecoupling-pin D, thereby securing a simultaneous movement between thecoupling-pins and the tumbler.

Journaled in suitable bearings beneath the platform of the car is acrank shaft or rod, F, which, after passing under the draw-head, isextended beyond the sides of the platform, and on the ends of the rodmay be formed cranks or handles ff, for operating the tumbler andcoupling-pins. Near the center of this rod, and directly beneath thedrawhead, is formed a bend or crank, g, to which is secured one end of aconnecting-rod, g, the opposite end (after passing through the opening)being secured to the lower end or long arm of 8 5 the tumbler E.

If desired, the cranks f f can be connected by rods or chains to the topof the cars, so that the coupling or uncoupling may be readily effectedwithout descending from the car, whichis specially desired infreight-cars. I do not wish to limit myself to the exact constructionabove referred to, for I have shown in Fig. 3 a single drawehead, H,provided with a coupling-pin, L, which is con structed in a mannersubstantially the same as that described above, and shown in Figs. 1 and2. V

The operation of my automatic coupler is as follows: The coupling-pinsbeing in the position shown in Fig. l, the coupling-link attached to anapproaching car is caused to enter one of the openings formed in thedrawcomes in contact with the projecting arms of thecoupling-pins,whichwill cause the for-' pins to approach each ward endsof the said other by means of the pin and slot formed in the arms 0 andd, thereby securing the link Within the draw-head. To uncouple the carsthe operator has only to draw upon the rod Z, Y

which will immediately release the couplingpins from their contact withthe coupling-link ed to operate substantially as herein set forth.

2. In an automatic car-coupler, the coupling-pin 0, having a portion ofits surface cut away, and having a projecting pin, 0, in com binationwith the coupling-pin D and the herein-described means for locking thesaid parts together, substantially as and for the purpose set forth.

3. In an automatic car coupling, and in combinationwith a doubledraw-head, the couplingpin D, having a portion of its surface cut away,and provided with a flat step and a projecting arm formed with aslotadapted to engage a pin formed on the projecting arm of the coupling-pinO, and a tumbler, E, all constructed to operate substantially as and forthe purpose herein set forth.

.4. In an automatic railway coupler, the tumbler E, constructedsubstantially as shown, in combination with coupling-pins D and C, and acrank-shaft and connecting-rod for operating said tumbler, substantiallyas and for \the purpose set forth. pins 0 and D, constructedsubstantially as shown, and atumbler, E, all construct- 5. In acar-coupler, a crank-shaft, F, located beneath the draw-head, incombination with a connecting-rod, g, tumbler E, and couplingpins 0 D,all arranged to operate substantially as and for the purpose set forth.

BEVLY ALLEN FISHER.
